UC2843D8TR Overview
With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. dc motor controller is suitable for 1 output generation. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). DC control operates at 12V~28V volts and has 12V~28V supply voltage. Suitable for a -40°C~85°C TA dc switcher. There is a switch at Up to 500kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of terminations with 8 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics will be returned if you search "UC2843". 8 pins are present on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 5V. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. 500kHz is the frequency of the switching controller. It is possible to set the input voltage as 25V for nominal working statuses. Current supplied to the controller should not exceed 25mA.
